The O-Train derives its name from the word "One," as the three provinces (Gangwon-do, Chungcheongbuk-do, Gyeongsangbuk-do) in the country's central inland region are connected by this one circular route. The train was designed with the theme of the four picturesque seasons of Baekdudaegan, Korea's biggest and longest mountain range that stretches from Baekdusan Mountain to Jirisan Mountain. The four-cabin train carries up to 205 people and includes separate seating options for families and couples to accommodate the needs of different passengers. There are also individual observatory seats for people traveling on their own. The train is well-equipped with various convenience facilities including a café, children's play area, toilets, etc. The train moves at the 165km per hour of speed, allowing passengers to reach Seoul to inland region quicker and easier than before. The exterior of the train is decorated with the pictures representing the beautiful scenery of Korea's four seasons, whereas the insides are dotted with highlights taken from Baekdudaegan mountain range.

There are many beaches having the name Myeongsasimi in Korea. While “Myeongsa” refers to “soft sandy beach,” it has a different meaning in Sinji Myeongsasimni Beach; here, it conveys “echoing beach,” because the sound of silvery sand swept by waves is known for spreading over 4km (“Simni” means “4km” in Korean). Befitting its name, the beach (150m in x_width) stretches over 4km. One of the most exquisite beaches along the South Coast, the beach is also shallow, ideal for family tourists. Bathing in the sand here is believed to be effective for neuralgia, arthritis, skin diseases, and athlete’s foot.

The 4th Tunnel was discovered on March 3, 1990. It is located 1,200m from the Military Demarcation Line in the demilitarized zone of South Korea. This is the only tunnel to be discovered that provides full access to tour groups. Educational instruction is given in the square outside the tunnel.

Cheongoksan Mountain (1,276m) is located to the southeast of Manggyeongdae on Taebaeksan Mountain. The hiking course goes along the ridge of the mountain from Neutjae in Socheon-myeon and winds past Hongjesa Temple, which (according to rumors) is where the great Buddhist monk Samyeong underwent spiritual training. Nearby is Baekcheon Valley, which has been designated Natural Monument No. 74, since it is the southernmost natural habitat of the cherry salmon. Also located in the vicinity are Goseon Valley (home to a huge primeval forest) and Cheongoksan Recreational Forest, which includes various leisure facilities such as a water park, work-out center, campgrounds, lodges, and more.

The 28-meter high Huibang Falls is a waterfall located below the Huibangsa Temple at Sobaeksan Mountain in Sucheol-ri, Punggi-eup, Yeongju-si, Gyeongsangbuk-do. It is located 700 meters above sea level about halfway up Sobaeksan Mountain. It is one of the must-see attractions on Sobaeksan Mountain, and is the No.1 waterfall in the whole Yeongnam (southeastern part of Korea) area. The water from the falls comes from Yeonhwabong Peak (1383 m), one of the sacred peaks of Sobaeksan Mountain. The water flows along the Huibang Valley and then plunges into the rocks below with a big splash, creating a breathtaking view for visitors.

Ganhyeon Resort is located where Seomgang River and Samsancheon River meet. The resort offers an amazing view, with the riverfront surrounded by white sand, oddly shaped rocks and lush forests with a 40 to 50-m high wall of rock formations along both sides of the river. The natural beauty of the area was also praised in the lyrical prose "Gwandong Byeolgok" by Songang Jeongcheol.

Gudambong Peak and Oksunbong Peak (alt. 372m) are widely known as two of the “Eight Scenic Views of Danyang." Gudanmbong Peak (lit. Turtle Pond Peak) gets its name from the reflection of its rugged cliffs on the lake below, which is said to look like a turtle. Oksunbong Peak (lit. Jade Shoot Peak), well known for its magnificent scenery, was so named because its white and mossy rocks stand high like fresh bamboo shoots. The old historic book Yeojiseungnam (Geographical Survey of Korea) describes how Kim Il-son, a civil officer in the Joseon Dynasty, greatly extolled the beauty of its marvelous ravines. Both Gudambong Peak and Oksunbong Peak offer spectacular views of Chungjuho Lake and Geumsusan Mountain.
